Capital Allowances Act 2001

Section 438: Expenditure on research and development

1518.This section is based on sections 137(3) and 139(1)(c) of CAA 1990. It sets out what is included and excluded from being expenditure on R&D and also permits just and reasonable apportionments of expenditure.

1519.Subsection (4) is more explicit than section 137(3) of CAA 1990, in that it only permits certain expenditure on a dwelling to be treated as on R&D. See Note 53 in Annex 2.

1520.Subsection (5) requires any apportionment to be “just and reasonable”. This is a change, see Change 40 in Annex 1.
